Lzc8650c Ic Datasheet | Pdf

Without proper thermal design, the LZC8650C will enter thermal shutdown or fail prematurely. The datasheet provides:

The ESOP-8 package has a thermal pad underneath. If this pad is not soldered to a large copper area (with thermal vias to an inner ground plane), the IC will overheat at currents above 800mA. The datasheet specifies the minimum pad size and via pattern.

The device regulates the LED output current by monitoring the voltage across a sense resistor on the source of the external MOSFET (CS pin). By operating in Boundary Conduction Mode, the controller turns the MOSFET on when the inductor current drops to zero, eliminating reverse recovery losses in the output diode and optimizing efficiency.
